The LT1252 is a low cost current feedback amplifier for
video applications. The LT1252 is ideal for driving low
impedance loads such as cables and filters. The wide
bandwidth and high slew rate of this amplifier make
driving RGB signals between PCs and workstations easy.
The linearity of the LT1252 is outstanding; it is unsur-
passed for driving composite video.
The LT1252 is available in the 8-pin DIP and the S8 surface
mount package. For higher performance and shutdown
operation, see the LT1227. For dual and quad amplifiers
with similar performance see the LT1253/LT1254.
